' VIBRATIVE LIQUID ATOMIZER AND MIXER- Specification of Letters Patent.

Patented Aug. 6, '1907.

Application filed December 20.1900, Serial No- 40,577. Renewed January 21, 1907. Serial No. 353,364.

To all whom it may concern:

Be it-kno'wn that 1,-JAMss WALLACE TYGARD, a Citi? zen oi the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Vibra'tive Liquid Atomizer and Mixer, of which the following is a specification.

The purpose of this invention is to disintegrate or atomize any liquid into minute individual particles so that the same will float in and become commingled with any fluid or gaseous substance, as air or gas, etc. thereby forming a saturated or mixed vapor. This method of vaporizing or atomizing liquid may be utilized for a variety of uses, such as surcharging the air entering a room or building with a definite proportion of moisture, for commercial or disinfecting purposes, or for manufacturing certain gases from liquid hydrocarbons. It

may also be advantageously employed in some forms of explosive motors? where a liquid actuating medium, such as gasolene or? petroleum, is employed. In this style of motor it is necessary to vaporize the charge and thoroughly mix the same with a certain amount of air before introducing the mixed charge into the expansion or explosion chamber.

The present invention covers a very simple and efficient device for accomplishing any of the above stated purpdses. The same consists in interposing a part or diaphragm in a fluid inlet pipe, in vibrating the same by the incoming fluid, or by extraneous mechanical'or electrical means at great speed, and in introducing the liquid in such position as to drop or fall on the rapidly vibrating part of diaphragm. This will throw the liquid medium immediately into vapor, and thoroughly mix and comminglc the same with the incoming fluid, thus rendering the mixture ready for use.

In the accompanying two sheets of drawings forming part of this application for patent, I have shown various Ways by which the invention may be practiced.

Referring to said drawings and in detail, Figure l is a sectional elevation of one form oi device, Fig. 2 is a transverse sectional view taken on the line 22 of Fig. .1, Fig. 3 is a transverse sectional view taken on the line 33 of. Fig. l, and Figs. 4, 5 and 6 are views similar .to

Fig. 1, illustrating modifications hereinafter described at length.

Referring first to the device shown in the first three figures, A designates a suitable inlet pipe, through which the fluid is drawn or forced. B designates an inlet for directing the liquid medium into the pipe A. The end of the inlet pipe is shaped to form a fine nozzle C from which the liquid medium will drip or flow in small quantity. D designates a reed, whichhas a suitable tongue or lip E, which reed is detachably fitted into the pipe A, and held in place therein by screw F. With this construction,- as the fluid rushes in through pipe A, the tongue E of the reed will be caused to vibrate at a high speed, and the liquid medium falling thereon from the nozzle (7, will be quickly vaporized, and thoroughly mixed with the incoming fluid.

-In Fig. 4 a modified construction is shown. In this construction a vibrating part of diaphragm E is pivotally fitted in a hole F cut in the pipe A. A spring G normally keeps the part E in one position. H designates a small bracket or arm which is secured to the pipe A. v A stop or projection I is arranged in this bracket to limit the movement of the part E. A small toothed wheel J is journaled on a stud or shaft J secured in said bracket H, and is rapidly rotated by a belt K from any suitable source of power. This will cause the part E to vibrate rapidly in the pipe A, whereby the action previously described will be obtained. a

In Fig. 5 a vibrating part or diaphragm E is shown as secured at its ends 'to a bracket H secured to the pipe A. This diaphragm E carries an armature E, under which is arranged an electro magnet L. A suitable intermittent or pulsating current of electricity is carried through the magnet. This causes the part E to vibrate at high speed to accomplish the result previously described. ln Fig. 6 substantially the same construction is shown, except that the end of the vibrating part E is secured in an extension M from the pipe A, and that the clectro-magnet L is also housed within this extension. 'A detachable screw-cap N allows access to these parts. This construction operates as those previously described.

The mechanical means shown to vibrate the surface may be employed when tllc pressure or draft of the fluid or gaseous medium is insuilicicni to vibrate the surface otherwise.

It will be seen that the various forms of mechanism which may be employed for practicing the invention are very simple and cilicicnt for the purpose.

Other forms and arrangements may be devised without departing from the scope of the invention as expressed in the claims.

Having thus fully dcscribed the invention, what I claim and desire to secure by Letters Patent is:-

l. A vaporizer :iud mixer for commingling minute particles of li uid and incorporating the same with a gaseous medium to form :1 moistened or saturated vapor for any of the purposes described, consisting of an inlet-pipe for liquid, a vibrating part with motion substantially trans verse to the direction of the feed of the liquid thereto.

I and which by its motion throws said liquid into fine 2. A vaporizer and mixer for the purposes described,.

consisting of an inlet-pipe for delivering liquid, a vibrating part whose motion is substantially transverse to'the direction in which the liquid is fed thereto, end an inlet pipe for the gaseous medium.

3. Aveporizer and mixer for the purposes described,

10 consisting of an inlet pipe for liquid having a nozzle from which the liquid is permitted to drop or fall, a vibrating part whose motionissubstentislly transverse to the talling liquid, and an inlet-pipe tor the gaseous medium.

In testimony whereof I have hereunto set my hand, in the 'presence of two subscribing witnesses.

JAMES WALLACE TYGARD.
